Why teams connect Couchbase and MarkLogic

Keep Couchbase and MarkLogic synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Couchbase and MarkLogic continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • 01 Write cleaned or enriched records from operational databases back into Couchbase collections that applications read.
  • 02 Sync Couchbase JSON documents into Postgres or a warehouse where analysts work with flattened relational tables.
  • 03 Write updates from operational systems back into the document hub to keep the canonical record current.
  • 04 Keep reference datasets and semantically linked entities aligned across downstream applications.

Common sync patterns

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

Cross-engine sync

Keep the same dataset live in both Couchbase and MarkLogic, so each workload runs on the engine that suits it.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

What you can sync between Couchbase and MarkLogic

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Couchbase objects MarkLogic objects How this pairing syncs
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. Collections Named groupings used to scope which documents a sync reads or updates. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. Semantic Triples RDF data stored alongside documents, queryable with SPARQL for linked-data syncs. Global Secondary Indexes is specific to Couchbase and Semantic Triples to MarkLogic — each maps to any object or custom field on the other side.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. TDE Views Relational projections of documents that let syncs read document data as SQL rows. XDCR replications is specific to Couchbase and TDE Views to MarkLogic — each maps to any object or custom field on the other side.
Full-text search indexes Search indexes over documents, relevant when syncing searchable content. Document Metadata & Properties Permissions, quality, and property fragments carried with each document. Full-text search indexes is specific to Couchbase and Document Metadata & Properties to MarkLogic — each maps to any object or custom field on the other side.
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. Databases & Forests Storage units that define the scope and placement of synced content. Buckets is specific to Couchbase and Databases & Forests to MarkLogic — each maps to any object or custom field on the other side.
Scopes Namespaces inside a bucket used to group collections, similar to schemas. Users & Roles Security principals that govern what an integration credential can read or write. Scopes is specific to Couchbase and Users & Roles to MarkLogic — each maps to any object or custom field on the other side.

How changes propagate between Couchbase and MarkLogic

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Couchbase MarkLogic Sub-second propagation

DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.

DeliveryEach detected change is applied to MarkLogic as a row-level write, with types converted between the two schemas.

MarkLogic Couchbase Interval-based propagation

DetectionStacksync polls MarkLogic for changes on an incremental schedule, reading only records changed since the previous pass. No exposed transaction log.

DeliveryEach detected change is applied to Couchbase as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Couchbase: Throughput is bounded by cluster sizing rather than API rate limits.
